i try to think as little as possible
- the issue i was having when i first started using MB was understanding how the different play panels and buttons related spatially to the playlist on the right, and that other play button on the main library... i must say i had to pay attention in the beginning
***
i was thinking about moving the play/stop/fwd/vol stuff from bottom to above the "now playing" on right
because thats what those buttons affect...
****
but i see that you are left with that display which shows the current playing song ... so i dont know if that would go well like a big thing up on top as in the following
crude mockup
theres cd artwork on the left there
but it might be missing a play/stop button in that area up top too...
the vol i feel should be up top, big, because it affects everything...
maybe change the colors of the now playing column and the big box at top too...
